Prefix all subfolders in a folder using Windows Batch Scripting

The following batch script shows how to prefixes all folders with "Java_".

@echo off

set "prefix=Java_"

REM The /D switch iterates over directory names only.

REM The * wildcard matches all folders.

FOR /D %%i in (*) DO (

    echo "%prefix%%%i"

)

@pause

To really prefix all subfolders of the folder, use REN instead of ECHO command with following minor change:

@echo off

set "prefix=Java_"

REM The /D switch iterates over directory names only.

REM The * wildcard matches all folders.

FOR /D %%i in (*) DO (

    REN "%%i " "%prefix%%%i"

)

@pause

Tips
